Patent Images

1. A neuromorphic system for image distortion correction, comprising:

  • a plurality of neurosynaptic core circuits that;

    receive a set of inputs comprising image dimensions and pixel distortion coefficients for at least one image frame via at least one input core circuit;

    map each distorted pixel to zero or more undistorted pixels by processing the set of inputs corresponding to each pixel of the at least one image frame by the at least one input core circuit, wherein mapping of each distorted pixel comprises a corelet of the at least one input core circuit estimating a closest pixel coordinate (x′

    , y′

    ) in a distorted image plane that a pixel (x, y) maps to under a selected metric and creating a neurosynaptic network within the plurality of neurosynaptic core circuits for routing corresponding intensity values of pixel (x′

    , y′

    ) to at least one output core circuit for output of the pixel (x, y); and

    route corresponding pixel intensity values of each distorted pixel to output undistorted pixels for each image frame via the at least one output core circuit.
